This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X250-100, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SUJ Adjustable Cylinder SUJ100X250-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X250-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 250mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X250-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X250-100
The AirTAC SUJ100X250-100 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 150-250 mm extend range from the 250 mm nominal maximum. The stop screw sets the end position; it is not a load lock.
This SKU is discontinued and drops in directly to the SAUJ100X250-100, sharing the exact bore, stroke, force, port, and SC-series FA/LB mounting. Note this non-magnet model cannot take a switch, and plain cylinders drift on air loss—use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X250-100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X250-100 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SUJ Adjustable Cylinder SUJ100X250-100 Is Used
Variable-Length Pressing
Trimming the extend stroke by up to 100 mm on-site allows a single 250 mm cylinder to press workpieces of varying heights without swapping the entire actuator.
Adjustable Diverter Arms
Diverter mechanisms needing different reach distances for changing product sizes can field-tune the extend end position within the 150-250 mm usable window.
Variable-Depth Stacking
Stacking stations can adjust the extend stop on-site to build varying pallet heights, using the external screw to set the precise end position per cycle.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X250-100 with the SAUJ100X250-100
To replace the discontinued SUJ100X250-100, order the direct replacement SAUJ100X250-100; the bore, 250 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting are identical. Choose the 100 mm adjust window when you need deep on-site extend trimming. Because this is a non-magnet SKU, it cannot take a sensor; if you need position detection, the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify your side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X250-100
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ100X250-100 FAQ
Yes, the SUJ100X250-100 is discontinued. The direct replacement is the SAUJ100X250-100, which matches the 100 mm bore, 250 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors, whereas the SUJ used legacy CS1-B/DS1-B.
The external stop screw provides a 100 mm adjust window, shortening the 250 mm nominal extend stroke down to 150 mm on-site. The stop sets end position only; it is not a load lock.
